W3Techs tells you what the web uses. TechSpy tells you what one company runs.
W3Techs is an authority on adoption statistics across millions of sites. TechSpy points at a single domain and returns its real stack, infrastructure, and a decision-ready read.
- Point at one domain, get its real stack — not a percentage across all sites
- DNS, DMARC, subdomains and hidden APIs W3Techs was never built to surface
- Every scan ends in a Verdict, Evidence and Implications, not a raw list
Free — no card, 30 scans/day.
W3Techs — the survey
TechSpy — the read · acme.io
HighVerdict
Modern Next.js front end backed by Segment and Intercom — but DMARC is set to p=none, so the domain is spoofable.
Evidence: Next.js on Vercel edge via JS-runtime fingerprints; Segment, Intercom and HubSpot in the marketing stack; DMARC policy p=none — monitoring only.
Implication: a polished growth stack with an unguarded email domain — a clear opening for a deliverability or security pitch.
An industry average won't tell you about the account on your list
W3Techs answers “what share of the web runs this?” — a trusted source for trends and citations. But a percentage across millions of sites says nothing about the one company you're about to pitch. TechSpy scans that company and tells you what it runs and why it matters.

Head to head
Not all checkmarks on our side — web-wide market-share stats and adoption trends are W3Techs' home turf, bolded below.
What only TechSpy does
The per-company depth a web-wide survey doesn't reach — turned into an action, not a statistic.
🔍
Sees through the SPA
JS-runtime fingerprints and HTTP headers read React and Next.js apps that leave HTML scrapers near-empty.
🧭
A read, not a list
Tools grouped by meaning, plus Verdict, Evidence and Implications with High/Medium/Low confidence — so you know what to do next.
